CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 253,432, dated February '7, 1882,

- Application filed July 5, 1881. (Model.) 1

. To all whom it may concern plan view of the same.

Similar letters of reference indicate corre sponding parts.

The object of this invention is to facilitate the opening of cans and promote convenience in adjusting the opener.

The invention consists in a can-opener constructed with a handle, a bar attached to the handle and having a curved point and a perforated lug upon its forward end, the swiveled screw having a thumb wheel upon its inner end, and the cutter having a shank made with a screw-hole to receive the swiveled screw and a perforation to receive the supporting-bar, whereby the cutter can be adjusted by the hand that grasps the handle, as will be hereinafter fully described.

A is the handle of the can opener, to the forward end of which is securely attached a bar,

screw, E. The rear end of the screw E is piv-- oted to the forward end of the handle A, and has a thumb-wheel, F, attached to it, so that the said screw E can be conveniently turned by the hand that grasps the handle A. The screw E passes through a screw-hole in the shank G of the cutter H. The shank G of the cutterH has a perforation formed through it to receive and fit upon the bar B, so that the cutter can be moved toward or from the point 0 by turning the screw E in one or the other direction. The cutter H is made in the shape of an arrowhead, as shown in Fig. 2, and its sides are rounded 011', so that when being used the said cutter will turn down the edges of the can-top along the opposite sides of the cut, leavingthe upper side of the said can top perfectly smooth.

In using the can-opener the point 0 is thrust through the center of the top of the can and the cutter is adjusted to make the cut at the I desired distance from the edge of the said cantop by turning the screw E in one or the other direction. The cutter is then forced through the top of the can and is carried around the point C as a center for any desired distance. In using the cutter to open square or oblong boxes or cans the point 0 is thrust through the top of the can near the center of one edge. The knife H is then adjustedin proper position and a semicircular cut is made in the top of the can in the manner hereinbefore described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A can opener constructed substantially as herein shown and described, consisting of the handle-A,the bar B, havinga curved point, C, and a perforated lug, D, upon its forward end, the swiveled screw E, having thumb-wheel F upon its inner end, and the cutter H, having in its shank G a screw-hole to receive the screwE and a perforation to receive the bar B, as set forth.
